Reply to comment by amitym in Ultramassive black hole over 30 billion times mass of our sun has been spotted. The discovery had been made possible thanks to a phenomenon known as gravitational lensing — the first time a black hole has been spotted in such a way. by Wagamaga

I really should have responded to the poster you were responding to rather than you as that’s the question I intended to address about feeling 0 g’s, not gravitational gradients on intermediate and stellar sized black holes.

It doesn't have to do with inertia. Astronauts orbiting Earth feel like they're falling, instead of feeling like they're being extruded into a thin bloody dribble, because the pull of gravity is effectively the same at their feet as it is at their heads.

That's not the case when very close outside the Schwarzchild radius of smaller black holes. But at 30 billion solar masses, the Schwarzchild radius is so far out from the singularity that the gravitational gradient is, as around Earth, negligible.

Reply to comment by Meajaq in Gut Bacteria Toxin Linked to Onset and Relapse of Multiple Sclerosis – Study suggests the onset and relapse of multiple sclerosis (MS) may be initiated by epsilon toxin from gut bacteria Clostridium perfringens. by swhelan_tn

But if you put these things into gelatin capsules, the same kind designed for OTC herbal supplements, they’re formulated to dissolve within the small intestine, which is where this particular bacteria and toxin are being produced. I’m not suggesting it totally ameliorates it, but I think it strongly stands to reason that it’d likely reduce numbers or severity some.

Reply to comment by soundscream in Firearms deaths involving preschool-aged children had increased at an alarmingly high rate in the United States in the past decade, but state laws may help curb shooting deaths among young children. by Wagamaga

My only other statement is I love when people that are so deep in gun culture that they think that knowing the technical difference between these guns is the point and they get lost in the weeds.

Point is that we're the only country on the planet that has this problem and that children are regularly dying in places that they should be safe. The fact that the number one cause of death for children and teens in the United States is guns is completely lost on people like you.

Rather have some sort of semantic conversation about style and type instead of the overall thinking that there's a problem with guns in general.

With a disease like MS very little is known definitively about the direct cause. The broad theory is that something triggers the immune system to attack the nerve cells causing severe scaring (sclerosis) which degrades or eventually completely blocks neuron function. The biggest puzzle has been what causes the blood brain barrier breach in this autoimmune reaction. However, given how much we are now uncovering regarding the gut microbiome link with brain function and mental health, it’s plausible that a Clostridium infection in the gut could open such a pathway.

After posting my comment above I went back to the literature and confirmed that doxycycline does indeed cover clostridium perfringens. I would be very interested to see a patient trial, but I don’t expect many pharmaceutical companies are lining up to discover a new disease treatment for a drug that has been in commercial use for more than 50 years.

I hope you're as adamant about not banning drag, trans, gay people in general, CRT or any of the other things that Republicans want to ban as you are about guns.

If it's not the guns, and banning them won't do anything then the rest of it gets thrown out with the bath water as well.

Reply to comment by and_dont_blink in Study Suggests Wild Blueberries Help Burn Fat. Results showed participants burned notably more fat after consuming wild blueberries. For example, fat oxidation rate rose by 19.7%, 43.2%, and 31.1% at 20, 30, and 40 min after cycling. by Wagamaga

Can you elaborate why the washout is irrelevant and what is loose about the study besides it being free living? The dietary changes that were instructed weren't highly likely to cause increases in fat oxidation to such a degree, except fasting and potentially alcohol reduction.

Well yeah that’s true but if it prevents growth on improperly chilled meats for 6, 12 hours etc. then it stands to reason the bacteria still doesn’t like them in the small intestine either. I don’t see how it’s likely to change?

As far as i know, the additional 100 calories on their own shouldn't induce a metabolic effect like increasing fat oxidation by up to 40% and reducing carb oxidation. Adding 100 calories into the control would be nearly impossible to skew the metrics they were investigating.

Since you're a researcher, is the washout really irrelevant as the other guy says? None of the changes the participants would've made during the washout would have increased fat oxidation and they weren't restricting a lot except colorful foods basically. Since they were required to provide food journals they could be accounted for, and even if they did eat some anthocyanins without reporting, why would the fat oxidation rates increase that after the powder was given? Wouldn't the increase have been lower or non existent if they still consumed large anounts of anthocyanins during the washout?

The Colt-AR15 as it existed was banned, but simply changing to a non-threaded barrel and a non-colapsable stock was all you had to do. Thats like banning red cars with 20inch tires and claiming that blue cars with 21 inch tires are completely different.

My point is the FAWB didn't and wouldn't stop this sort of stuff from happenning.

Uvalde cops were cowards and the ar-15 was an excuse. The ar the person in tennesse had didn't stop those cops from going in.
